RALPH L. FORD, OF CHICAGO, ILLINOIS, ASSIG-NOR TO INTERNATIONAL HARVESTEB COMPANY, A CORPORATION OF NEW JERSEY.

DISK AND SCRAPEB MOUNTING.

Application filed May 7, 1920.

T 0 all whom it may concern:

Be it known that I, RALPH L. FORD, a citizen of the United States, residin at Chicago, in the county of Cook and btate of Illinois, have invented certain new and useful Improvements in Disk and Scraper Mountings, of which the. following is a full, clear, and exact specification.

This invention relates to improvements in furrow openers of the twin-disk typesuch as used in connection with loose-ground lister planters, and more particularly to the manner of mounting such disks and their scrapers on the runner-frame of the planter.

The objects of my invention are to provide a mounting for each disk of the pair that will afford a wide range of adjustment as to angle and vertical position relative to its support and to mount the scraper for each disk so that it can readily be adjusted in accord with any change of position of the disk.

I accomplish these objects by securing the stub axle for each disk to the runner frame of the planter by a novel form of mounting including a universal joint of the ball and. socket type connecting each spindle to its supporting plate and constructing this mounting in such a way that adjustment is effected by loosening a single nut, and by employing a novel form of mounting for the disk scrapers, including a pivoted bracket carrying the scraper arms, constructed in such a way that adjustment of the disks can,

easil be followed by the scrapers.

ith these main and other incidental ob jects in view my invention consists of the organization, details of construction, parts,

or their equivalents herein described, and more particularly defined in the claims.

Having reference to the drawings: Fig. 1 is a plan view of a runner frame with parts in section showing the disk and scraper mountings.

Fig. 2 is a side view of a runner frame showing the supporting brackets for the stub axle and scrapers.

Fig. 3 is a side view on a reduced scale with a disk and scraper in working position.

Fig. 4 is a horizontal section through one of the disk mountings.

Fig. 5 is a detail view of one of the attaching plates.

F ig. 6 is an end view of the plate shown in Fig. 5.

Serial No. 379,594.

Fig. 7 is a detail view of a bearing sleeve.

Fig. 8 is an end view of Fig. 7 looking toward the left, and

Fig. 9 is a detail view of the spindle head.

In the embodiment illustrated on the drawings, my invention is shown in connection with the usual runner frame of a planter including the boot 10, runner 11, and runner braces 12. The boot 10 has a bracket 13 formed on or secured to its forward side. This bracket consists of an elongated body formed with a vertically extending transverse slot 14 which has its opposite margins on each face of the bracket formed with central grooves or depressions 15. The opposite faces of the bracket 13 are preferably corrugated as shown on Fig. 2. Each face of the bracket carries an axle supporting plate 16 both of which are secured thereto by bolts 17 which pass through the brackets and through slots 14:, permittingvertical adjustment ofboth plates 16, and disks carried thereby, in unison. As the plates 16 and attached parts are the same on each side of bracket 13, only one will be described.

The plate 16 has its inner face corrugated to interlock with the bracket face and has a pair of vertically spaced lugs 18 which bridge the slot 14 and are received in the grooves 15 to serve as guides and retain the parts in proper position during vertical adjustments of the plate 16 on the bracket. At the middle of the inner face of the plate 16 and between the lugs 18 there is formed a substantially hemispherical or cup-shaped socket 19 (Fig. 5) with its transverse axis nearer the rear edge of the plate.

At the middle of the opposite face of plate 16 a cylindrical boss 20 is formed, on the axis of which there extends an opening 21 which communicates with socket 19 at a point somewhat offset from its transverse axis, owing to the lateral position of the socket on the plate as above referred to and as seen in Fig. 5. The cylindrical boss 20 is formed with an inclined face extending from its front edge in a plane at an angle of approximately 15 with the plate and with corrugations radiating from the opening 21. A bolt 22 extends from the opening 21 and has a plano-convex washer 23 mounted thereon with its plane face resting against the head of the bolt and its convex face reposed incll 31. its

larger end sleeve 24 has an angular overhanginp fiange 26 and its outer and smaller 2? which is end is engaged by a 'Washe drawn into position by nut 28 to clamp the stub azile composed of e and bolt 'or spindle 22 in adjusted position on the supporting plate An oil duct and socket for reception of the stem 0:? an oil cup is provided on the sleeve 94 as at 29. The tlangiie lnib 3O oi" a furrow opening disk 31 mounted for rotation on the sleeve 2d the flange 26 overhan ing the larger end of the ,hub and serving to exclude dirt from the bearing, While washer 27 engages the aller endand retains the hub in position. hub cap 32 isreinovably secured to disk and flange as by bolts j v isovide'nt from the structure ust de- .ub scribed that loosening; ct .n t 28 perinits sleeve 92 4.- to be to on spindle and that such turnino' will by reason of ti 3 opi'ed t'aces oi" boss ene the sleeve 2% and the universal joint between the spindle 2:2 the supportingplate 16, ijesi'i'lt a variati in the angle at which tlie stu'b axle pro ects from the support. in. order to permit adjustment of the inaccord with adjustment of he furrow disks, a scr 'a iier supporting; bracl et 34 is pivotedfat its forward end by bolt 35 between the runner braces 12. This bracket isshaped to contorni to the space between the runner braces and "has a transverse slot 36 its rear end torfined on an are about the axis 35. A bolt 37 passes through this slot and 'both runner braces and serves to clainpthe bracket in adjusted position. The upper 'Iface'oii bracket 84: has a seat 38 formed at its rear end in which the horizontal portions scraper arms 39 are received in overlapped relation e arms are formed with longitudinal slots 40 to permit lateral ad ustment and a bolt passes through i these slots and the bracket and serves to olanip the arms in adjusted position. The i 'ertical portions of arms 39 extend down- Wardl v and rearwardly toward the disks 31 and each carry a scraper blade 42 loosely secured thereto at 43 and held in resilient some with the disk by spring 43 en- 'circliuga headed pin which is iii-zed to the scraper blade and is freely movable scraper an opening provided in the end oit against which splin t l bears. this construction and arrangement of supporting bracket and scraper arms, adjustment ot the bracket on its pivot moves the scraper arms on the arc of the pivot 35 and gives their]. the combined vertical and lateral adjustment needed to keep the blade at the proper place in all adjustn'ients of disks likely (0 b required in ctical use.
